Title: Recording disk reproducing device
Inventor: FUKUMITSU AKIRA
IPC: G11B17/049
Filed: 1982-05-21
Abstract: PURPOSE:To simplify the structure and to improve the operability, the mechanical performance and reliability of a reproducing device, by controlling the power supply of a player, the up-down movement of a turntable, the feed action of a pickup arm, etc. by the operation of just a control lever. CONSTITUTION:The 1st and 2nd cams 36 and 37 of a control lever 34 turn on a power supply switch 48 and a play switch 49 respectively. Then a turntable starts its revolution, and at the same time a motor 57 turns to feed a carriage 26. Thus a worm wheel 67 is turned via a belt 61 and a worm 60, and a pinion 66 is also turned together. A rack 261 of the carriage 26 engages the pinion 66, and therefore the carriage 26 moves by the revolution of the pinion 66 along a guide ball 27. Then the pickup arm is carried in the diameter direction of the turntable. Thus the reproduction is performed.

Filed: 1989-04-03
Abstract: PURPOSE:To prevent coating liquid from sticking on an opposite roller too much by providing means which apply liquid for offset prevention on the surface of the lower heat roller of a couple of fixing rollers where a recording medium is passed with its toner image transfer surface down. CONSTITUTION:The coating means 22 and 23 apply the liquid for offset prevention on the surface of the lower heat roller 19 of the couple of fixing rollers 18 and 19 where the recording medium P is sent in contact with the facing-up surface of an image formation body 5 and passed with the toner image transfer surface down. The reverse surface of the heat roller 19 is made to contact with the liquid surface in a liquid tank 22 which contains the liquid for offset prevention and liquid which sticks on the heat roller 19 too much is scraped off and returned to the liquid tank 22 by a blade 23, thereby easily applying the liquid. Thus, the liquid flows down and then the liquid sticks on neither the recording medium P nor the other roller 18 too much.

Title: Arc cutting method in gravity welding machine
Inventor: KAYA RIYUUTAROU
IPC: B23K9/10
Filed: 1981-06-02
Abstract: PURPOSE:To perform arc cutting inexpensively with a small-sized and lightweight device in gravity welding by detecting the voltage change by a sharp drop or rise of voltage and cutting the arc. CONSTITUTION:When in a gravity arc welding machine a welding rod which descends by melting melts down to the terminal part, that is, the part where its covering material exposes, the voltage drops sharply. If the spacing between base materials and the end of the welding rod is increased by obstructing and stopping the holder of the welding rod during melting and descending with an obstruction (that is, the arc is elongated), the voltage rises sharply. This voltage change is detected with a voltage relay and the arc current is interrupted. According to this method, the arc cutting can be controlled electrically in lieu of conventional mechanical control and therefore the construction of guiding rails and sliders is simplified, the setting of gravity is facilitate and particularly the need for any automatic inversion mechanism is eliminated.

Title: Fm receiver
Inventor: SATOU TERUO
IPC: H04B1/16
Filed: 1979-07-05
Abstract: PURPOSE:To reduce deterioration due to signal distortion by controlling a local oscillation frequency in accordance with a phase error between input and output signals of an intermediate frequency filter. CONSTITUTION:From the input side of an intermediate frequency filter, a received signal is led to the 1st input terminal of multiplier 8 via limiter circuit 9 and from the output side of the intermediate frequency filter, the received signal is supplied to the 2nd input terminal of multiplier 8 via limiter circuit 4. Then, multiplier 8 outputs a signal that corresponds to a phase difference between the input and output signals of the intermediate frequency filter. The phase characteristics of the intermediate frequency filter can be compensated by controlling local oscillating circuit 7 on the basis of the output signal of the multiplier. Detection part 5 uses a phase- shift multiplication type FM detecting circuit. In this case, a phase shifter can easily be realized by a double tuning circuit. The characteristics of this phase shifter  should be compensated as well as those of the intermediate frequency filter.

Title: Ghost elimination device
Inventor: ITO SHIGEHIRO
IPC: H04N5/21
Filed: 1990-03-30
Abstract: PURPOSE:To more surely eliminate a high frequency ghost by emphasizing a high frequency component of a video signal prior to processing of the video signal. CONSTITUTION:A filter 21 is provided to a pre-stage of an A/D converter section 1, a filter 22 is provided to a post-stage of a D/A converter section 4 and a filter 23 is inserted between a waveform fetch section 5 and a subtractor 7 respectively. The frequency characteristic of the filter 21 is formed in the frequency characteristic which a high frequency component is emphasized linearly with respect to the low frequency component, resulting that the high frequency component is emphasized. Thus, when the signal is A/D-converted at the conversion section 1, the quantization accuracy of the high frequency region is improved more than that of the low frequency region. When no ghost is included in the signal, the signal is not processed at all by a digital filter section 3 (processing of zero coefficient), the result is inputted as it is to a D/A converter section 4, where the signal ia D/A-converted. The frequency characteristic of the filter 22 is selected so as to be complementary with the frequency characteristic of the filter 21. Thus, the signal passing through the filter 22 has an original flat frequency characteristic.

Abstract: PURPOSE: To facilitate a recording timing to be taken, by providing one beam detector and delay means in a beam recording devive with the direction of arrangement of plural recording beams nonrectangular to a scanning direction.  
     CONSTITUTION: A plurality of recording beams B1WB4 arranged nonrectangularly to a scanning direction are guided to beam detector 7 with reflective mirror 6 at the end of the scanning line. When the beams cross the edge of shielding plate 8, detector 7 is suddenly irradiated by the light shielded so far, and detector 7 produces an electrical output corresponding to this beam irradiation. Detector 7 detects the timing of rising of the incident beams at the start and produces the detected signals stepwise integrated.
